SKU: PBBPB1112-N
MPN: PB1112N
The Power Bond Balancers BBM 7.24-inch steel harmonic balancer (model PB1112N) is a precision-engineered crankshaft damper designed specifically for internal balance Mopar RB-series engines. This balancer is essential for managing harmful vibration frequencies that develop at high RPM, thereby extending engine life and improving overall driveability.
The 7.100-inch outer diameter fits OEM specifications for direct fitment to compatible Mopar big-block applications. Harmonic balancers work by absorbing torsional vibrations generated by the crankshaft firing cycle. The PB1112N is engineered for Mopar RB-series blocks and must be paired with an internally balanced crankshaft assembly, ensuring optimal performance and durability.
Mopar RB-series engine builders and restorers rely on matched balancer specifications to prevent dangerous harmonic imbalances that can accelerate component wear. With a weight of 7.07 lbs, this balancer delivers the necessary rotational inertia for stable harmonic control without excessive parasitic load, making it ideal for engine rebuilds and restorations.
